You start out with a tin. Small tins work great, but so do larger tins, lunch boxes or altoid tins. (If you ever see this kind of chocolate you should definitely buy it because the chocolate is so amazing with wine and the tin is fun to alter. Total win win. I bought 3...)
You start by tracing an approximate shape onto your patterned paper. This works best with lighter weight paper. You can use cardstock weight pp, but it is much easier with the lighter paper. I would like to point out that this tin has a curve to the lid. If you are using an altoids tin or something similar it will not have this slope and will be much easier to alter. You would just be able to cut for the lid and then put ribbon or a strip of paper (or even paint) on the side edge. Notice how imperfect my line is. You DON'T have to be exact, by any means.
Cut out your paper and coat your tin with Mod Podge. Just a note about Mod Podge: It is a sealer/adhesive and comes in different finishes. I usually use a matte finish, but they also make glossy and glitter finishes as well. It is available at JoAnns, Michaels, WalMart...
You want to put the paper on the tin and cut slits aroung the corners.
The slits allow you to fold around the slope. Again, if you are doing a tin without a sloping lid you could skip to the next step.
Tuck your ends in all the way around.
Trim as closely as possible with your scissors. Don't stress about being exact. You don't need to be.
Use a nail file to trim your excess paper.
Coat your project with Mod Podge and add your embellishments (I used die cuts here).
That is all there is to it, folks!
